Now, for a few days, I have been experiencing random, but very painful, cramps. I was on my week 1 when I took the 2 pills in the same day. I am now into week 2. During my period week, I did not have sex nor have I had sex after missing the pill (I've been stressed so I haven't really been in the mood anyway). I had my period as normal (though it was lighter).
Is this a common side-effect for missing one day and taking 2 the next day?
